Transcript of County Level Determination of Fracturing Risk
COUNTY LEVEL DETERMINATION OF FRACTURING RISKFinal project, CE385K.4
Nick Kuzmyak
Fracturing in the US• Hydraulic fracturing continuing to expand
• Practices steadily getting more refined• Water
treatment/recycling• Non-traditional water
sources• Microseismic imaging
Extent of Shale Plays
Relevant Aquifers
Population Density
Given the background info…• So, what should we be concerned about regarding
hydraulic fracturing activity?• Proximity to large/dense population centers• Concurrence with aquifers• Shale plays with high fracking activity
• Current goal of project:• Figure out which counties are the most at-risk• Determine what legislation is available there• Be able to target action
Most At-Risk Counties• A function of weighted factors:• Aquifer depletion• Fracturing activity level• Proximity to densely
populated areas• Others to be added
At-Risk Counties: Activity, Density, Aquifer Depletion
Still To Do• Calculate true areas of polygons to get accurate
measures of density• Wells per square mile• People per square mile
• Create intrapolygon rasters:• Well density over a shale play• Well drawdown over an aquifer• Quantified risk over entire US
• Expand “risk equation,” weight factors• Cross-reference at-risk counties with current laws
